摘　　要：针对青藏高原的特殊环境和区域化探异常查证周期长的特点,开展了现场分析测试的适应性研究。选择便携台式X荧光仪,对仪器进行了标定,考察了仪器的稳定性,确定了样品的加工粒级为-160目和粉末状试样。通过亚卓查证区现场分析,其结果与室内分析结果基本相符,达到了试验研究目的,确定了一种及时提供分析结果的现场分析方法,采用该方法可有效缩短异常查证周期。Research was carried out under the special conditions of the Tibetan Plateau, with the consideration of the time-costing fea-ture of regional geochemical follow-up. The portable XRF spectrometer was used in the research, and the instrument was calibrated and checked for the stability. The sample particle size of -160 mesh for sample processing and powder samples was determined. The result of in-situ experiment, which was conducted in Yazhuo anomaly follow-up zone, is basically in accordance with the conclusion of labora-tory analysis. This is an in-situ analytical method, which can quickly provide analytical results and effectively shorten the work period for anomaly follow-up.
